Recently, some citizens discovered that two sets of yellow footprints have been added to the escalators of some subway stations in Beijing, one on the left and one on the right. According to relevant subway operating companies, this sign aims to remind passengers that they do not need to "walk left and stand right", but can choose to stand side by side and remind them to stand firm and hold onto their feet. When taking an escalator, it is a long-standing public transportation habit to walk on the left and stand on the right. Even regarded as a symbol of civilized travel. It is mainly for the convenience of allowing some people in a hurry to go ahead from the left side. But in recent years, more and more cities are calling on people to change this habit. On the one hand, walking on elevators can easily create safety hazards, increasing safety risks such as falls and stampedes. On the other hand, practice has shown that this method also increases the maintenance cost of elevators and even affects their service life. As previous data has shown, 95% of elevator damage is caused by uneven force distribution in elevators due to the "left row, right standing" principle. Regarding the adjustment of these travel rules, the media has actually discussed it several times in recent years. But in reality, it is not easy to completely change a long-standing habit of public transportation. Even 'standing on the left' has been integrated into the 'muscle memory' of many people. In this situation, it is indeed necessary to provide more guidance to help more people break free from the misconception of 'walking left and standing right'. Two sets of yellow footprints have been added to the escalators of some subway lines in Beijing, one on the left and one on the right. This detail demonstrates a more proactive attitude towards correction and may be worth emulating in more places. After all, compared to the text version of the rules posted on the wall, this tangible guidance measure that can reach everyone will have a more direct reminder effect. On this basis, further steps can be taken. From the perspective of social ideology, the most crucial aspect of changing the "walking on the left and standing on the right" is to make more people aware that "walking" in elevators is dangerous and not advocated. So, subway stations can clearly remind everyone not to walk on escalators through broadcasting and other means. In this way, passengers' understanding will be more intuitive and the moral pressure that passengers who do not stand on one side should not bear will be reduced. That is to say, to change the mindset of 'walking on the left and standing on the right', the first thing to change is' walking ', followed by solving the problem of how to stand more scientifically. Looking at it from a different perspective, when there is no trace of "walking" on the escalator, it may be a more commendable form of travel civilization. At the same time, there are also some practical issues involved here. For example, some people are used to walking on escalators, which may also be related to the inconvenient setting of some escalators. This issue should be included in the rectification of subway management. The formation of a social public habit is inevitably shaped by many factors. To change it, it is necessary to find ways to guide and cultivate the necessary "new environment" for developing "new habits" from multiple perspectives. For example, in addition to reminders from subway management, it can also be included in safety education. If children know from a young age that "walking left and standing right" is not advisable and that walking on escalators is unsafe, it is naturally less likely to form a wrong behavioral habit. This actually involves the "keeping up with the times" of safety education and the connection between education and safety management. In addition, the process of changing from a widely accepted and followed "rule" to a subject of correction reflects the importance of a society's ability to maintain rational reflection on all "rules" and "conventions". That is to say, creating a tolerant and even encouraging social atmosphere for open discussion of existing rules can help society optimize rules in a timely manner and move away from potentially incorrect habits on a larger scale. This is equally worthy of attention. (New Society)
